Global wireless entertainment publisher JAMDAT Mobile Inc. (NASDAQ: JMDT) announced today the launch of Tetris(R) in Brazil, marking the first time that the wireless version of the international hit is available in South America. JAMDAT's version of the classic puzzle game is available today on VIVO, the largest wireless carrier in South America. One of the most widely played interactive games of all time, Tetris is a simple, highly addictive puzzle game. Players attempt to manipulate block-like pieces called "Tetriminos" as they drop into a well. As the Tetriminos fall, players attempt to neatly arrange them into a horizontal row. When the row is complete, it is removed from the well, and the player's score increases. "Tetris has international appeal, and we are excited to bring it to wireless users in South America for the first time," said Mitch Lasky, Chairman and CEO of JAMDAT Mobile Inc. "Our Brazilian launch is a significant step in our continuing effort to bring Tetris and our other world class content to wireless gamers throughout South America, an increasingly important part of the global wireless market."
